Product details
Overview
TLV707335DQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 3.35 V fixed output voltage in a 1-mm × 1-mm X2SON-4 (DQN) package. It delivers ±0.5% DC accuracy, 70 dB PSRR at 100 Hz, and stable operation with only 0.1 µF output capacitance - enabling compact, cost-effective power delivery for battery-powered RF subsystems in portable electronics.
For engineers reviewing the TLV707335DQNR datasheet, TLV707335DQNR pinout, TLV707335DQNR application, or TLV707335DQNR equivalent, key selection criteria include dropout voltage at 150 mA (220–270 mV), thermal shutdown/overcurrent protection, enable-pin logic thresholds (VIH = 0.9 V, VIL = 0.4 V), and compatibility with low-bias-voltage ceramic capacitors in space-constrained layouts.
Technical Context
The TLV707335DQNR uses a PMOS pass transistor architecture to achieve ultra-low quiescent current and fast load transient response. Its internal bandgap reference and error amplifier maintain regulation across –40°C to +125°C junction temperature, with no minimum load requirement.
Unlike standard LDOs, it achieves stability with 0.1 µF effective output capacitance - reducing board area and BOM cost - while delivering high PSRR (50 dB at 1 MHz) and low output noise (45 µVRMS, 100 Hz–100 kHz) critical for RF-sensitive analog and digital circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.35 V ±0.5% - ensures precise biasing for 3.3-V logic, RF front-ends, and ADC references without external feedback. |
| Max Output Current | 200 mA - supports moderate-power microcontrollers, sensors, and wireless transceivers in handheld devices. |
| Quiescent Current | 25 µA - extends battery life in always-on or low-duty-cycle applications such as wearables and IoT edge nodes. |
| Dropout Voltage | 220 mV @ 150 mA (3.35 V output) - enables operation from single-cell Li-ion (3.0 V min) or two-cell alkaline sources with margin. |
| PSRR | 70 dB @ 100 Hz, 50 dB @ 1 MHz - suppresses switching noise from DC/DC converters feeding the LDO input. |
| Output Noise | 45 µVRMS (100 Hz–100 kHz) - minimizes jitter and SNR degradation in clock buffers, audio codecs, and precision ADCs. |
| Enable Threshold | VIH = 0.9 V, VIL = 0.4 V - compatible with low-voltage GPIOs (e.g., 1.8-V or 2.5-V I/O domains) without level-shifting. |
Pinout & Package
Package: DQN (X2SON-4), 1.0 mm × 1.0 mm, 0.4 mm height, thermal pad on bottom. Pin 1 = OUT, Pin 2 = GND, Pin 3 = EN, Pin 4 = IN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers stable 3.35 V; requires ≥0.1 µF ceramic capacitor to ground for stability - enables use of small 0201/0402 caps in dense layouts. |
| GND (Pin 2) | Power ground reference | Low-impedance return path for load and internal circuitry; connects to thermal pad for enhanced heat dissipation (RθJB = 159.4°C/W). |
| EN (Pin 3) | Active-high enable control | Drives >0.9 V to enable; <0.4 V to shut down (ISHUTDOWN = 1 µA); supports sequencing and power gating in multi-rail systems. |
| IN (Pin 4) | Unregulated input supply | Accepts 2.0–5.5 V input; requires local 1-µF ceramic decoupling to minimize high-frequency noise injection into the LDO core. |
Key Features
| Feature | Design Value |
|---|---|
| 0.1 µF stability | Eliminates need for large, expensive bulk capacitors - reduces PCB area by >50% vs. traditional 2.2–10 µF LDO designs. |
| 25 µA quiescent current | Enables >1-year battery life in coin-cell-powered sensors (e.g., BLE beacons drawing 10 µA average). |
| 70 dB PSRR @ 100 Hz | Rejects ripple from buck converter switching frequencies and their harmonics - preserves signal integrity in RF receivers. |
| Thermal shutdown + current limit | Prevents damage during short-circuit or overtemperature events; auto-recovery allows graceful fault handling without system reset. |
| ±0.5% output accuracy | Meets tight tolerance requirements for ADC references, PLL VCO supplies, and memory I/O rails without calibration. |
Applications
| Smartphone RF Front-End | Wearable Sensor Hub |

IC Role / Device Role / Timing Role: Fast-transient LDO ensuring stable supply during burst-mode radio transmission and vibration actuation. Use Value: Load transient response <100 µs (1 mA → 150 mA) prevents brownout resets; 200 mA capacity supports dual-radio coexistence. | Use Scenario: Isolating and regulating USB-peripheral power (e.g., IR blasters, HDMI CEC adapters) from noisy main 3.3-V rail. IC Role / Device Role / Timing Role: Noise-filtering LDO decoupling USB PHY and microcontroller I/O from shared SMPS output. Use Value: 50 dB PSRR at 1 MHz attenuates 2-MHz buck converter ripple; shutdown current <1 µA meets USB suspend leakage limits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC707335DQNR | Same pinout and electrical specs; differs only in tape-and-reel packaging (TI internal variant code). | No functional difference; identical performance and qualification. | Select when sourcing from TI-authorized distributors with specific reel-size requirements. |
| MCP1703T-3302E/MB | 3.3 V output (not 3.35 V); 250 mA max; 3 µA IQ; requires ≥1 µF output cap; PSRR 60 dB @ 100 Hz. | Lower noise sensitivity but higher dropout (350 mV @ 150 mA); less suitable for Li-ion headroom-limited designs. | Choose for ultra-low-power applications where 3.3 V suffices and 1-µF cap footprint is acceptable. |
Compared with TLV707335DQNR, TLC707335DQNR is functionally identical and interchangeable, while MCP1703T-3302E/MB trades lower quiescent current for reduced PSRR, higher dropout, and stricter capacitor requirements - making TLV707335DQNR preferable for RF-critical, space-constrained, or wide-input-voltage portable systems.

FAQ
What is the output voltage tolerance of TLV707335DQNR over temperature and load?
The TLV707335DQNR maintains ±0.5% DC output voltage accuracy across –40°C to +125°C junction temperature and 0–200 mA load range, as specified in the Electrical Characteristics table. This tolerance holds under all recommended operating conditions (VIN = VOUT(nom) + 0.5 V or 2.0 V, whichever is greater), ensuring reliable operation in thermally demanding portable environments without external trimming.
Can TLV707335DQNR operate with a 0.1 µF output capacitor, and what type is recommended?
Yes, TLV707335DQNR is explicitly designed to be stable with an effective output capacitance of 0.1 µF or greater. X5R or X7R ceramic capacitors are recommended due to low ESR and minimal bias/temperature derating; a 0.1 µF 0201 or 0402 chip capacitor is sufficient, enabling ultra-compact layouts where board space is constrained.
What is the maximum input voltage rating for TLV707335DQNR, and what happens above that limit?
The absolute maximum input voltage for TLV707335DQNR is 6.0 V. Exceeding this rating may cause permanent damage. Under recommended operation, VIN must stay within 2.0 V to 5.5 V. At 5.5 V input and 3.35 V output, the device sustains full 200 mA load with typical dropout of ~200 mV - well within safe thermal limits given its RθJA of 208.1°C/W.
Does TLV707335DQNR include reverse-voltage protection, and how should reverse bias be handled?
No, TLV707335DQNR does not include reverse-voltage protection. Its PMOS pass transistor has an intrinsic body diode that conducts uncontrolled current if VOUT exceeds VIN. For applications with potential reverse bias (e.g., hot-swap, backup battery), external protection - such as a series Schottky diode or dedicated reverse-protection IC - is required to limit reverse current to ≤5% of rated output current.
How does the enable pin (EN) behave during power-up, and can it be left floating?
The EN pin of TLV707335DQNR is active-high with VIH = 0.9 V and VIL = 0.4 V. It must never be left floating: an unconnected EN pin may float near the threshold and cause erratic enable/disable behavior. For always-on operation, tie EN directly to IN; for controlled sequencing, drive it from a clean GPIO with defined logic levels - avoiding weak pull-ups or RC delays that could violate timing margins.
